Application filed July 25,

To @ZZ fte/0m t 'may concern.'

Be it known that I, O'rTo H. Josiir, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, State of hio, have invented certain Anew and useful improvements in Rims, of which the followinois a specification.

llhis invention relates to vehicle wheel rims and more particularly to tire-supporting rims of the so-called "quick-detachable7 type. which have a tire-retaining flange at one edge, and a tire-retaining side ring adjacent the other edge which is detachably secured to the rim, to facilitate the removal or replacing of a tire.

One of the objects of the invention is to provide simple and effective means for securing the detachable side ring in position upon the rim.

Other objects of the invention and the features of novelty will be apparent from the following description, taken in connection with the accompanying drawings, in which L Figure 1 is a 'fragmentary side elevation of a rim embodying` my invention, certain of tie parts of the rim being broken away, to more clearly disclose the structure;

Fig. 2 is a fragmentary bottom plan view of the structure shown in F ig. 1;

is fragmentary side elevation, similar to Fig. 1, but showing a modified structure embodying my invention; and

Fig. r-1 is a view in perspective of one of the parts shown in F ig. 3.

In the drawings, 11 indicates a vehicle wheel rim having a tire-securing flange 12 at one edge thereof and being provided, adjacent its other edge, with a circumferential channel or groove 13 to receive a side ring 14 which is transversely split, as shown at 15, and has a base or web portion 16 thereon which extends inwardly therefrom and is adapted to be seated in the groove 13 in interlocking relation with the outer wall 17 of the groove. Adjacent its ends, the side ring 14 is provided with lugs 18 and 19, which extend through apertures Q0 and 21 which are formed in the rim at the bottom of the groove 13, and are provided with transverse slots 22 and Q, respectively, in which the ends of a locking member 24 are adapted to engage, to hold the ends of the 1919. Serial No. 313,176.

side ring fromradially outward motion. A portion of the rear edge of each of the lugs 18 and 19 is inclined forwardly and inwardly, as shown at 25, for a purpose which will be later. described, and abrupt shoulders 2G are formed on said edges adjacent the base of the ring to co-operate with the rim at the ends of the apertures 2O and 21, to vhold the side ring from circumferential motion on the rim. A web portion 27 between the apertures 20 and 21 serves to support the ends of the side ring and will also cooperate with the forward edges of the lugs 18 and 19 to hold the side ring from circumferential motion on the rim.

A bridge member or support 28 is secured to the channeled portion of the rim, by rivets 29, or in any other suitable manner, and deflected away from the rim so as to underlie the lugs 18 and 19, when they are in seated position. The locking member 24 isv pivotally mounted in the bridge member 28, the body portion thereof having oppositely extending tongues 30 which are adapted to engage in the slots 22 and 23 when the locking member is in the position shown in i? ig. l, but will be disengaged therefrom when the member has been moved substantially -ninety degrees from such position. That part of the member 24 which extends through the support QS is preferably circular in cross-section, to form a good bearing surface, and a pintle 34- is formed on the locking member 24 and is iournaled in an opening 85 in the web portion 2T, to furnish more rigid mounting of the locking member. A lever arm 31 is provided to rotate the member 24 to and from locking position, and has a non-circular opening therein which fits over a correspondingly shaped portion of the member 2%, the inner end of which is riveted against the lever, to hold the parts in assembled relation. Adjacent its ends, the lever 31 is provided with a cuppedr portion 32, which is adapted to engage over the head of one or the other of the rivets 29, to hold the lever 31 and the locking member 24 in ring-securing pos-ition, and an opening 33 is formed in the lever 31 so that a screw driver or other instrument may be inserted therein to facilitate the movement of the lever and the locking member to and from locking position.

In a modified structure shown in Fig. 3, the locking member 24 may be provided with -a pintle 34:3, similar to the pintle 341i shown in Fig. 1, and journaled in an opening 352L in the web portion 27, to furnish a more rigid, mounting for-the locking member, and tongues 30a, are formedV on the locking member, similar tothe tongues 30 orthe member 24, and for the same purpose. order to'rotate the locking member 24a, a head 36 of non-circularv shape, preferably hexagonal, as shown, may be provided; such head having a non-circular opening therein,l

in which a similarly shaped extension S7-on the locking member fits, and the inner end of theextension 37 is riveted over, as shown at 38, to engage the hexagonal head to hold the parts together.

When itis vdesired to replace the side ring upon the rim, one end of the ring `is seated upon the rim so that the Ilug thereon extendsr through its aperture 20 or 21, and the ring is then progressively seated around ythe cir-A cumference of the rim, the side ring being expanded suiiciently to permit the web portion 16er the ring to be lifted over thesi'de wall 17 of the groove 13. I'l the lug on that end of the ring which is last seated vdoes not accurately register with its aperturey 20 or :21, the entry of the lug in its aperture, when radially inward pressure is applied tothe end' of the ring, will be facilitated by the engagement oi' the inclined rear edge 25 or' i the lug with the rim at the end of the aperture. Then the lugs 18 and 19 are'seated in their apertures with the shoulders 26 thereon engaging with the rim, the ring will be held fromfcircumferential motion, andthe locking member 24, or 24a, can be turned to position vthe endsy thereof in the slots 22 and 23 to hold the ends of the ring from radially outward motion.

`and having an axialextension thereon journaled in said rim.

2. In a vehicle wheel of the class described, the combination of a tire-carrying rim having a pair of apertures therein separated by a web portion, a split side ring detachably seated on said rim and having lugs thereon extending through said apertures, a support.l

rigidly secured to said rim on opposite sides H of said apertures and underlying said lugs,

and means engaging said lugs to secure said ring in seated position comprising a rotatable member journaled in said support and said web-portion.

3. In a vehicle Wheeloi' the class described, the combination of a tire-carrying rim apertured adjacent one edge thereof, av split side ring detach ably secured on said rim and having lugs projecting inwardly through the apertured portion of said rim, a support onA the interior of said rim rigidly secured thereto on opposite sides of said apertured portion, circumferentially, and underlying said lugs, and means arranged between said lugs and rotatably mounted on a radially extending axis on said support and adapted to, in one position, engage both of said lugs and prevent removal thereof from said apertured portion of the rim, and in another position, to be disengaged from said lugs.

In testimony whereorn I aiiix my signature.
